Staging environment

The best M5.1 staging topology is Cloudflare for edge/docs, Vercel for Next.js API/Studio, Postgres for state, Databricks for warehouse aggregation, and Temporal Cloud for Harness agents.

Start order

1. Deploy the docs site to your documentation domain.
2. Create Cloudflare KV and R2 resources.
3. Provision Postgres and apply migrations.
4. Deploy apps/api and apps/studio to Vercel.
5. Deploy manifest, exposure, and audit-export workers.
6. Create Databricks catalog/schema fx_staging.fx.
7. Flip Harness dependencies from link: to published packages for the worker image.
8. Deploy the Harness worker connected to Temporal Cloud.
9. Seed staging data.
10. Run M3/M4/M5 live smokes and keep them green for at least seven nights.

See the repository runbook at docs/runbooks/staging.md for detailed commands.
